It enables a system with a 13 standard Ethernet adapter to interoperate with a RoCE 14 adapter or with another system running the RXE driver. 15 Documentation on InfiniBand and RoCE can be downloaded at 16 www.infinibandta.org and www.openfabrics.org. (See also 17 siw which is a similar software driver for iWARP.) 18 19 The driver is split into two layers, one interfaces with the 20 Linux RDMA stack and implements a kernel or user space 21 verbs API. The user space verbs API requires a support 22 library named librxe which is loaded by the generic user 23 space verbs API, libibverbs. The other layer interfaces 24 with the Linux network stack at layer 3. 25 26 To configure and work with soft-RoCE driver please use the 27 following wiki page under "configure Soft-RoCE (RXE)" section: 28 29 https://github.com/linux-rdma/rdma-core/blob/master/Documentation/rxe.md 30
